To all who/1.a t may con-cern Be it known that I, WILLIAM C. Kinn, a citizen or the United States, and resident of Suffern, in the county of Rockland and State of New York, have invented certain new and useful Improvements in Switch Stands, ol" which the following is a specification. y

This invention relates to railway switch stands, and particularly to the means for holding the interlocking portions of a switch stand against accidental disengagement.

Switch stands'of the type shown in the drawings are usually known as litamapo switch stands and comprise means permitting and controlling automatic tl'irowing` of the switch points by a trailing locomotive or v car in combination with means for operating` the switch manually independently ot the automatic means, the said automatically operated means and manually operated means being normally interlocked except during the period when the switch points are being thrown manually.

rlhe present invention relates particularly to means for yieldingly holding the automatic means and the manually actuated means in locking engagement and tor preventing accidental disengagement thereof from jars or concussione due to passing trains or other causes.

A further object of the invention is to provide nieans whereby the switchman may be apprised when the switch point is thrown intoits operative position in contact with the running rail and the moving parts of the switch stand interlocked.

A further object of the invention is to provide an enclosed mechanisml which will be secure against accidental misplacement and protected against malicious' tampering.

Still another object oli' the invention to provide simple, compact and self-contained mechanism which will hold the interlocking parts under yielding pressure, readily pei mitting manual operation of the switch but preventing accidental movement sutlicient to disengage such parts.

Various other objects oilt the invention will be more fully set :forth in the following description of one form of switch stand embodying my invention shown in the accompanying drawings, in which:

Figure l is a view in `perspective of a switch stand embodying my invention;

It will be understood. that this invention is applicable to switch stands of various types and designs, but for purposes of illus tration the inventionr is shown as applied to the switch stand' described in detail in Patent No. 882,024, granted March 17, 1908, to l?. W. Snow and myself as joint inventors. In this switch stand the spindle l, which may carry a lamp or a target or other signal, is rigidly connectedtothe switch points preferably through a screw eye 2 by means of aconnecting rod fastened to the switch vpoints (not shown); The satety device', `ormeans for controlling automatic movement oE the switch points is housed within a iframe or casing 8 forming the base otthe switch stand, and comprises a bearing block 41 provided with central bearing within which the spindle is freely rotatable.

The bottom 'of the block l is provided with a star member 5 which is always in engagement with oppositel'y disposed rollers 6. Said 'rollers are mounted in vokesor 'frames and yieldingly held in engagement with the star member'by springs 7. -The arrangement of these parts is such th at any movement of the block will compress the springswhich will ai'ltomatically `tend to return the block to 'its originalposition until the points of the star member pass the ycenter line of the rollers, whereu'pon'the action of the springs will tend torotate the block further and in the vsame directionl until the rollers again come to rest'fintermediatethe star points, therebyy throwing and holding the switch point against the running rail.

The upper part tot the star or bearing block projects above the top ofthe housing and is provided with'squared sockets 8 An Qris pivoted as-at 9a to ahlock 10 rigidly secured to ori formed integral with the spindle so as tofhave vertical movement with respect to the spindle. The bottom of this'arm is adapted to seat in the sockets 8 thereby interlocking the automatic control means with the' manuallyloperated means. The arm projects a suitable distance beyond the star block and-may be operated manually or it may be operated -bymeans of the cam lever l1,4 pirated as. at; .lf2 t0 ,the-,base The @am surface@ @sieve/riem.' moraliteit of kwer 1m e 1 melma parallel to the track will raise the ann from onehof the sockets in the star b1ock, rotate thc spindle to throw the end then permit the ann te celeb inlthe nexteooket.

Preferably also the abutment is provided with a lug 18 having an eye 19 formed therein; toeceive suitable fastening means Such as a padlock so the arm may be held permanently in its adjusted position.

By meaps of this arrangement I have prouided a simple, compact and self-contained mechanism which holds the spindle and the mn in engagement with the automatic safety meant under a constant butyielding pressure sucient to counteract any concussions or jars to which the switch may be subjeoted A relatively stiff spring may be used without increasing appreciebly the amount ot em't required te reise the erm preparatory to manual. operation of the switch but which willcauee the erm to snap backrinto its socket under sufficient pressure to make a noise that will apprise the switchman when the switch has been completely thrown, The spring is entirely enclosed so that accidental misplaoement thereof or malicious tampering therewith is impossible.

AlthoughY I have shown and described a preferred arrangement and combination of parts embodyingmy invention it is obvious that `numerous changes and modifications may be made therein without departing from the 's iritA and` scope of the invention, pxiovidedn efmeans set forth in the followmg claims beemployed.
